Okay, so I have read some threads on this issue, and then read some more of them. I have been unable to locate a thread that matches my issue exactly, and about $200 later and still no resolve, I am turning to all of you for some guidance.

I am getting a single bong intermittently, then the evic displays "check TPM system", then the tire pressures are displayed. All pressures match exactly, none of them flash, and the separate light in the gauge cluster does NOT come on. I have removed all the wheels for cleaning a couple of times in the last 6 months, while doing this, although I am not losing any pressure at any wheel, I have bubble checked for leaks, none found. I have replaced two of the sensors, one due to corrosion and one that my local NTB tech said "this one is probably the bad one because it took much longer for my tool to read it" so I did. Darn it! same warning again two days later.

I have also lowered pressures, one at a time, and only slightly, in an attempt to make sure that each transponder was seeing the correct tire, and yes, they all are seeing the correct positions, no switching pressures or anything abnormal to be noted within the system.

So, if apparently nothing is out of order, what do I look for next? Are there any tests I have missed? I certainly don't want to start throwing transponders, and really don't want to have to do what my tech buddy mentioned yesterday (computer), but that was obviously a shot in the dark.

HELP! I am at a loss at this point, out of cash now too since I will be buying tires soon . Any ideas? Any and all guidance is appreciated.

Now as far as this TPMS issue - it sounds strange. So you are saying everything is working properly, but it still "bongs"? Seems like it might just need to be reset. I'm not sure if that could be as simple as a fuse pull, or if it would require a scan. I'll check my dealer manual and see if I can find something.

Do you have any codes? Sometimes you can still have codes stored even though the light isn't on.

I do think the TPMS brain can get out of whack sometimes. I had a tire installer break one of my TPMS in my summer wheels, so it was "bonging" and showing "0" accurately. But the strange thing was that when I put my winter wheels on (different set of wheels and different set of TPMS, all working properly), my car still wanted to think that I only had 3 operational TPMS, so it would chase the "0" around to all four wheels all of the time. Maybe a month later it FINALLY settled down and registered all four wheels in my winter set properly. So I don't know - I think it definitely has some gliches. Seems like a reset or reboot is needed.

Nope, no codes per Predator diag feature. Yes, one bong, sometimes, on thing I can relate the bongs to would be that it seems to happen more often the cooler it is, hence I thought it was a bad sensor battery, and what I figured was the slow response from the NTB tech's tool. That would be sweet if there was a fuse pull to reset this! I am tempted to just go out and disconnect the battery cables for a while. Is there anyone in OUR (yes,I am now a member as well) with a starscan?

Not sure about the starscan. I can find out.

I've attached some reading for you. This is from an '06 dealer service manual. Maybe this helps?

its not just you, i have the same issue. bought new wheels with new sensors, they display the correct tire pressure but every time i drive the car....BONG...then evic shows that all wheels have correct pressure. no codes, i gave up trying to figure it out.

Give this a go it may work but at least you will know for sure once you have tried it. Disconnect your battery for around 1 hour then reconnect it. This will reset most of your codes including the TPMS then take the car for a drive around 40mins to 1 hour on a highway or somewhere that you can stay above 60 klms per hour I think that is around 35 mile an hour and I think you might find the TPMS problem goes away. At least I hope it does for you. Worth a try and cost you nothing except time and a bit of fuel. um last of all I noticed you replaced one sensor was it the same MHZ as the others. not sure what yours are but mine are 433 mhz.

My sensors are the 315MHz frequency considering it is an 06'. Now that you have given me a glimpse of hope that this will work, I am headed out to disconnect the battery right now! Thank you for the reply!

If disconnecting bat does not do the trick, then you will need to use a scan tool to clear the TPMS brain. I was told by a chrys mech that sometime this is caused when you use brake and throttle at same time. Something else you may try and that would be to locate each pickup unit and check wiring for solid connections.
